WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 707,449, dated August 19, 1902.

Application filed December 5, 1901. Serial No. 84,776. (No model.)

To all whom "(it may concern:

Be it known that I, OVIDE OUELLETTE, of Lowell, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Window-Screens, of which the following is a specification.

This ,invention has for its object to enable a window-screen to be supported by the lower sash of a window in such manner that it can be-either raised and lowered with the sash or can be adjusted independently of the sash to close the opening caused by the raising of the sash.

Theinvention consists in the improvements which I will now proceed to describe and claim.

Of the accompanying drawings, forming a part of this specification, Figure 1 represents an elevation of the inner side of a portion of a window-casing, showing the lower sash and a screen connected therewith in accordance with my invention. Fig. 2 represents a section on line 2 2 of Fig. 1. Fig. 3 represents a perspective view of a portion of the lower sash and one of the screen-guides thereon. Fig. t represents a perspective view of a portion of the screen, showing a portion of one of the runners thereon. Fig. 5 represents a perspective view of one of the runner-securing devices. Fig. 6 represents a section on line 6 6 of Fig. 1. Fig. 7 represents a sectional view showing means for detachably se curing the screen-guides to the lower sash and for detachably securing the runners to the screen. Fig. 8 represents a view similar to Fig. 7 on a larger scale and showing one of the screen-guides and the runner thereon in section. Fig. 9 represents a perspective view of the screen-guide shown in Figs. 7 and 8. Fig. 10 represents a perspective view of the runner shown in Figs. 7 and 8.

The same reference characters indicate the same parts in all the figures.

In the drawings, a represents the lower sash of a window, and b the upper sash.

c 0 represent guides affixed to the inner sides of vertical rails of the lower sash, said guides, as here shown, being of substantially tubular form in cross-section and each provided with a longitudinal slot 0. The guides are shown as provided at their ends with ears 0 which are screwed to the sash a. It is obvious, however, that the guides may be constructed and secured to the sash in any other suitable way.

(Z represents a screen which has on its outer side runners 6, formed to enter and slide in the guides c, said runners having in this embodiment of my invention contracted necks 6', adapted to move in the slots 0' of the guides. Each runner e is preferably a partially-formed tube having a longitudinal slot in one side and is secured to the sash by means of plates of the form shown in Fig. 5, each plate having a central boss 6 which enters the interior of the tubular runner e, a neck c, which passes through the slot of the runner e, and ears a which are screwed to the screen-frame. The runnere maybe soldered or otherwise permanently secured to the bosses e to prevent it from slipping thereon. The runners 6 preferably have a sufficiently close fit in the guides to enable the screen to be supported by friction with the sash when the latter is raised in case it is not desired to have the screen close the opening below the sash, the runners sliding with sufficient ease in the guides to enable the screen to be moved downwardly to close said opening when the lower sash is raised, as shown in Fig. 1.

f represents a flexible guard-strip attached to the bottom rail of the lower sash and formed to bear upon the outer side of the screen, as indicated in Figs. 2 and 6, to prevent the passage of insects between the screen and the lower rail of the sash.' The guardstrip f may be made of any suitable material and is here shown as a strip of fringed textile fabric, the tips of the threads composing the fringe bearing against the outer side of the screen. g 9 represent similar flexible guard strips attached to the edges of the screen and bearing yieldingly against the inner sides of the casing-strips h, which confine the lower sash. The strips 9 prevent the passage of insects between the edges of the screen and the casing-strips.

In Figs. 7, 8, 9, and 10 I have shown means for detachably connecting the screen-guides to the lower sash and for detachably connecting the runners c with the screen, to the end that the screen-guides can be readily applied of the sash a.

to and removed from the sash, so that they may be stored away when their use is not required, and to the end, further, that a screen of ordinary construction may be equipped with runners without adaptation of the screen and frame to the runners. The guides c are of the general form previously described, except as to the means for securing them to the sash. Each guide has at its lower end a bent car 0 adapted to enter a slot 0 formed for its reception in the bottom of the lower rail The guide is provided at its upper end with a hook 0 which is adapted to spring into engagement with a detent c", affixed .to the top of the meeting-rail of the sash a. To engage the runner c with the sash, it is only necessary to insert the ear 0 in the slot 0 and spring the hook 0 into engagement with the detent c. The ear 0 is sufficiently flexible to enable the guide to be tipped outwardly at its upper end from the sash, so that in detaching the guide from the sash the hook 0 may be first disengaged from the detent c and the guide swung outwardly until the hook clears the meeting-rail, after which the guide may be moved downwardly to withdraw the ear 0 from the slot 0 The runner e is provided at its lower end with an upwardly-projectin g hook e, which is formed to engage the lower end of the screen, and at its upper end with a downwardly-projecting book 8 which is formed on a piece of springwire having a coil e the hook a being thus adapted to be sprung upwardly out of engagement with the upper end of the sash when the runner is to be disconnected from the screen and to spring downwardly into engagement with the upper end of the screen in connecting the runner to the screen. The hooks e and e are secured to blocks (2 inserted and secured in the end portions of the tubular runners c.

It will be seen that by the construction shown in Figs. 7, 8, 9, and 10 the screen can be readily applied. to and removed from the sash without disfiguring or requiring any conspicuous change in the appearance of the sash. 1

I claim 1. A window-sash having screen-guides on its inner side, and a screen having runners engaged frictionally with said guides, whereby the screen may be raised and lowered either with the sash or independently thereof.

2. A window-sash having screen-guides on itsinnerside,a screen having runners engaged with said guides, and adapted to be raised or lowered either with the sash orindependently thereof, and a flexible continuous inwardlyprojecting guard on the bottom rail of the sash, formed to bear yieldingly on the outer side of the screen.

3. A window-sash having screen-guides on its inner side,a screen having runners engaged with said guides, and flexible guards on the edges of the screen, formed to bear on the window-casing.

4. A window-sash having screen-guides on its inner side,a screen having runners engaged with said guides, a flexible guard on the bottom rail of the sash, formed to bear yieldingly on the outer side of the screen, and flexible guards on the edges of the screen, formed to bear on the window-casing.

5. A window-sash having slots in the bottom of its lower rail, detents on the top of its meeting-rail, and sash-guides having bent ears at their lower ends formed to enter said slots, and spring-hooks at their upper ends formed to spring into engagement with said detents.

6. A window-sash having screen-guides on its inner side, and a screen having runners e11- gaged with said slides, said runners having hooks at their ends adapted to detachably engage the upper and lower ends of the screen.

In testimony whereof I have affixed my signature in presence of two witnesses.

OVIDE OUELLETTE.
